The manufacturer reserves the right to make technical
modifications without prior notice.
This product should only be fitted by a qualified plumber to NVQ (National Vocational
Qualification) or SNVQ (Scottish National Vocational Qualification) Level 3. Should
the installation be completed by a non-qualified person then the guarantee may be
considered invalid.
For a claim made under our warranty written certification of your installers credentials
can be required. For further information or to find a qualified installer in your area
please visit the Institute of Plumbers website - www.iphe.org.uk
At present, to be a plumber you need to follow the National Vocational Qualification
(NVQ) route (Scottish National Vocational Qualification - SNVQ - in Scotland). These
qualifications are made up of theory and practical work in the classroom/purpose built
training facility and work based experience with a working plumber. Colleges should
help students find a work placement, although many students organise it themselves.
The S/NVQ qualification works in levels. All recently qualified plumbers should hold
S/NVQ Level 2 as basic with Level 3 as the preferred level. Level 2 will give you the
foundation you need for a career in plumbing and teach you domestic plumbing to a
satisfactory level. Level 3 is more comprehensive and deals with domestic,
commercial and industrial plumbing along with aspects such as gas - if you want to one
day set up your own business, this is the level to reach. The Institute of Plumbing and
Heating Engineering, and the industry as a whole recommends that all plumbers reach
a minimum of Level 3.
Reaching Level 3 has other advantages. The Institute runs a Master Plumber
Certificate, which only those attaining Level 3 or equivalent can reach as long as they
have the relevant experience as well. Those with S/NVQ Level 3 can (once in
membership with the Institute for five years as a Member MIPHE) gain Engineering
Technician EngTech status with the Engineering Council (UK).

General Installation Requirements.
The installation must comply with regulations of the Local Water Authority as contained in
their bylaws. All of the taps in this range are single flow (the hot and cold water mix in the
body) and should therefore be supplied with hot and cold water at balanced pressures,
both from the tank or both from the mains (via a combination boiler for example). If the taps
are not supplied at balanced pressures then the mixer will not function correctly. It will also
be necessary to fit non-return valves on both hot and cold feeds.It is very important that all
pipework is flushed thoroughly after installation to avoid damaging the ceramic discs.
Minimum/Maximum working pressure
These taps are suitable for high and low pressure installations They are fitted with a quarter
turn ceramic disc cartridge which provides a good flow rate with very smooth movement.
To ensure that the mixer works adequately under low pressure, the cold water storage tank
should be at least 2 metres above the highest installed position. The maximum water
pressure is 6 bar (note: mains cold water is normally supplied at between 2 and 3bar). For
installations where the mains pressure exceeds 6 bar a pressure reducing valve should be
fitted.
The tap is fitted with a flow straightener for use in low pressure installations. If your water
is supplied at high pressure you may prefer to change the nozzle to an aerator.
Approvals
All products are manufactured using materials tested and approved under the Water Bylaws
Scheme and comply with requirements of British Standard 5412:1996 where applicable.
Preparation and byelaw requirements
These taps are single flow so the hot and cold water mix in the body. Water byelaws require
that where the hot water is supplied from a tank and cold from the mains, non return valves
are fitted on both hot and cold pipes as close as possible to the tap. These are not supplied.
Where combination boilers are fitted it is only necessary to shut off the incoming mains and
turn the boiler off and non return valves are not required.
WARNING
Before installing the new mixer it is essential that you thoroughly flush through the
supply pipes in order to remove any remaining swarf, solder or other impurities.
Failure to carry out this simple procedure could cause problems or damage to the
working of the mixer.
These hints have been prepared for your guidance, you must exercise due care at all times.
We do not accept responsibility for any problems that may occur through incorrect
installation.

INSTALLATION INSTALLATION
First shut off your water heating system then, with your mains stop cock closed,
open the lowest hot and cold taps in the house and allow to run until the cold storage
tank and pipes are empty (the hot water storage cylinder always remains full).
Where combination boilers are fitted it is only necessary to turn off the boiler and
shut off the incoming mains.
Fitting isolating valves to the inlet feeds is recommended for ease of maintenance.
INSTALLATION
Remember to turn off the mains water supply before connecting to any
existing pipe work.
Warning! Please check for any hidden pipes and cables before drilling
holes in the wall
!
Mounting plate
A recess must be made in the wall to accommodate the mounting plate, mixer and
flexible hoses.
Place the mixer in position, check to see if any alterations are needed to the existing
pipe work.
Secure the mounting plate into the recess in the wall.
Connect the water supply to the tap with hot water on the left and cold on the right.
(When viewed from the front).
Once you have satisfied yourself that there are no leaks, switch on the water heating.
!
Valve
Apply a narrow bead of clear silicone sealant around the back edge of the cover
plate and carefully press into position.
ATTENTION
Having first checked all new connections, turn on the mains stop cock, close all taps
except the new mixer and as the system starts to refill check for leaks.

CLEANING THE CARTRIDGE
The concealed cartridge should give trouble free service, but in the event of any problems,
servicing is straight forward.
To remove the cartridge.
Pull off the screw cover on the mixer handle and undo the screw with a hexagonal key,
but do not remove, pull off the handle. Unscrew the cartridge cover and carefully using
the correct size spanner unscrew the retaining nut and remove the cartridge. Wash the
cartridge with clean running water and make sure that any trapped debris has been
removed. Dry and lightly grease the seals (only use silicone grease) replace the cartridge,
retaining nut, cartridge cover followed by the mixer handle. Re tighten the handle screw
and replace the screw cover.
The chrome and gold plate we use on our taps is very durable, nevertheless care should
be taken when cleaning them. They should be cleaned only with warm soapy water
followed by rinsing with clean water and drying with a soft cloth. All finishes are vulnerable
to acid attack and some strong substances such as household cleaners, disinfectants,
denture cleaners, hair dyes, wine making and photographic chemicals can cause the
surface to go black or peel.
